IB Mathematics Applications & Interpretation (AI) SL Internal Assessment Example

The exploration is well structured with a clear introduction, body, conclusion, and supporting sections, so the reader can follow the investigation easily.

The student's line of argument is generally coherent and logically developed, especially in the way they move from initial correlation work to a revised measure of success.

Most material is relevant to the inquiry, and the inclusion of tables, graphs, and appendices supports the main thread of the exploration.

The investigation is not fully seamless because the student repeatedly switches between seasons and episodes, which weakens the logical flow.

There are structural inconsistencies such as skipped numbering, duplicate section labels, and a largely blank page.

Some sections are more repetitive than necessary, which reduces conciseness and makes the development feel less precise.

The student uses mathematical notation appropriately in most places, including variables, correlation, normalisation, and regression notation.

The exploration makes effective use of multiple representations such as tables, scatterplots, formulas, and worked calculations.

The student's communication is generally clear and readable, with equations and tables integrated in a way that helps the reader follow the argument.

There are several notation inconsistencies, especially the repeated confusion between seasons and episodes.

Some symbols and formula statements are not fully consistent, such as the intercept formula and the changing labels in the composite-score work.

A few representations are useful but not yet sophisticated enough, particularly where extreme values or dataset changes are not fully explored.
